Given the frequency of hacks and data leaks these days, chances are good at least one of your passwords has been released to the wild.

A new Chrome extension released by Google today makes it a little easier to stay on top of that: Once installed, Password Checkup will simply sit in your Chrome browser and alert you if you enter a username / password combination that Google “knows to be unsafe.”

The company says it has a database of 4 billion credentials that have been compromised in various data breaches that it can check against. When the extension detects an insecure password, it’ll prompt you with a big red dialog box to immediately update your info.

It’s handy, but users might wonder exactly what Google can see — to that end, Google says that the extension “never reveal[s] this personal information.”

If you are using an old Operating System with no security updates, using a third-party DNS will be protection from phishing attacks

And, yes, you can get rid of geography-based content restrictions and web censorship
